STEAM MOTOR-ENGINE.

SPECIFICATION forming part of Letters Patent No. 282,071, dated July 31, 1883.

Application led January 2, 1883. (No model.)

To all whom it may concern).-

Be it known that I, HARvEY F. GAsKILL, of Lockport, in Niagara county, New York, have invented certain Improvements in Steam Motor-Engines, of which the following is a specification.

The object of my invention is to produce simple, compact,v and economical steam-motor.

The invention consists in acertain construction of the frame of the machine, as will be speciically stated in the claim at the end hereof.

rIhe principal elements which go to make up my frame are as follows, viz: two cylinders, one of which serves as a bed for the other; (these cylinders may be high and low pressure, so as to constitute a compound cngine;) bearings for a crank-shaft in front of the cylinders; standards for supporting a beam between the cylinders and the crank-shaft strut-ties or 2o equivalent devices for connecting the standards to the cylinders.

The drawing shows a side view of an engine containing my invention and appliedto working pumps in a pit or well. i

Inthe drawing, O is the base-casting of the frame. A is the low-pressure cylinder.

E is the high-pressure cylinder, mounted on cylinder A as a foundation or bed.

P and It are standardsto support the bearings of the beam-shaftj. v

J is a circular beam.

His a guide on which moves the cross-head h. l) is a similar guide for cross head d. Links connect these cross-heads and their pis- 3 5 ton-rods with opposite points of the beam.

Cylinder E takes live steam at its admission ports at N N and exhausts into cylinder A. As the pistons move in opposite directions, the steam-passages connecting E and A are short and direct and connect adjacent ends, so that 4o there is no loss by condensation and expansion in long passages.

f is a pillow-block or bearing for the crankshaft G. F is a fly-wheel on shaft G. The inner standard or beam-shaft support R extends 45 to the pillow-block f.

I and Q are strut-ties connecting the standards with the cylinders.

gis a rod connecting the crank to the beam and to the same point of the beam to which 5o the low-pressure piston-rod C is connected.

B B are pumps; Z, the valve-box of one of the pumps; B', the suction, C', the discharge; M, the air-chamber.

p are the pump-rods.

p are connecting-rods joining the pump-rods p with points p of the beam. The points p are opposite each other and at right angles to the points of connection of the piston-rods.

What I claim is- 6o The frame composed of the two cylinders, arranged one above the other, the standards P and It, the pillow-block, and the strut-ties connecting the cylinders and the standards, substantially as described.
